Dell's warranty on their Ultrasharp line can't be beat. They will replace the monitor if it has any bad pixels, and pay for shipping both ways.

When I received my first 2 about 6 or 8 months ago, the DVI port on one of them was a little out of line (it still worked though). I called up my Dell rep on a Thursday around noon, and they overnighted me a replacement that I received Friday morning about 22 hours after I called. Now I will say that it shipped from Dallas and I'm only a state over in Little Rock, but still...

All I did was pack the old monitor in the box the new one came in, slap on the UPS sticker that they sent along, and gave it to the UPS guy that they sent out for pickup. I didn't even have to wait for our usual UPS person.

I do want to say that we (our company) do buy a lot of Dell products, and I have our Dell rep on speed dial, but I have heard many impressive stories from regular consumers.
